How its Linux Boot Process works ? 🕵🏻‍♂️

🔌 When we turn on the power, BIOS or UEFI firmware is loaded from non-volatile memory, and executes POST (Power On Self Test).
💽 BIOS/UEFI detects the devices connected to the system, including CPU, RAM, and storage.
💿 Choose a booting device to boot the OS from. This can be the hard drive, the network server, or CD ROM.
📀 BIOS/UEFI runs the boot loader (GRUB), which provides a menu to choose the OS or the kernel functions.
🖥 After the kernel is ready, we now switch to the user space. The kernel starts up systemd as the first user-space process, which manages the processes and services, probes all remaining hardware, mounts filesystems, and runs a desktop environment.
📟 systemd activates the default. target unit by default when the system boots. Other analysis units are executed as well.
🎚The system runs a set of startup scripts and configure the environment.
📱The users are presented with a login window. The system is now ready.

💾A Linux file system is the method and data structure that Linux uses to control how data is stored and retrieved on a disk. Without a file system, data placed in a storage device would be a large body of data with no way to tell where one piece of data ends and the next begins. The file system is what allows Linux to organize data into files and directories, making it easier to access and manage
📲 Main Directory's Structure:
/root directory (/) is the topmost directory in the Linux file system hierarchy. It serves as the starting point from which all other files and directories branch out. Every file and directory on a Linux system can be accessed by following a path from /
/bin Essential user binaries
/etc Configuration files
/home User home directories
/var Variable files
/tmp Temporary files.

Linux's flexible file system design allows for multiple types of file systems to coexist and be used according to the needs of the system or storage.

Looking to break into Linux System Administration but currently only know how to ls and pray?
Don’t worry — we’ve all been there. 🙃

Here’s a completely free course to get you started: https://training.linuxfoundation.org/training/introduction-to-linux/

💻 60+ hours of content
🧪 Hands-on labs (because we learn by breaking things)
🏅 Completion badge (so you can flex on LinkedIn)
♾️ Lifetime access (for when you forget a command and Google betrays you)
💰 $0 (finally something in tech that doesn’t require a credit card)

Fun fact: Linux runs over 90% of servers and cloud infrastructure.
Translation: If you want to be in DevOps, CyberSec, or a SysAdmin, Linux is like oxygen… you kinda need it.

Also, once you understand Linux, your AWS bill will still be high — but at least you’ll know why. 😅
